Components' name and namespace overrides

It is possible to override the namespace where kube-prometheus is going to be deployed, like the example below:

local kp = (import 'kube-prometheus/main.libsonnet') +
{
  values+:: {
    common+: {
      namespace: 'monitoring',
    },
  },
};

If prefered, it can be changed individually by component. It is also possible to change the name of Prometheus and Alertmanager Custom Resources, like shown below:

local kp = (import 'kube-prometheus/main.libsonnet') +
           {
             values+:: {
               common+: {
                 namespace: 'monitoring',
               },

               prometheus+: {
                 namespace: 'foo',
                 name: 'bar',
               },

               alertmanager+: {
                 namespace: 'bar',
                 name: 'foo',
               },
             },
           };

{ 'setup/0namespace-namespace': kp.kubePrometheus.namespace } +
// Add the restricted psp to setup
{
  ['setup/prometheus-operator-' + name]: kp.prometheusOperator[name]
  for name in std.filter((function(name) name != 'serviceMonitor' && name != 'prometheusRule'), std.objectFields(kp.prometheusOperator))
} +
// serviceMonitor and prometheusRule are separated so that they can be created after the CRDs are ready
{ 'prometheus-operator-serviceMonitor': kp.prometheusOperator.serviceMonitor } +
{ 'prometheus-operator-prometheusRule': kp.prometheusOperator.prometheusRule } +
{ 'kube-prometheus-prometheusRule': kp.kubePrometheus.prometheusRule } +
{ ['alertmanager-' + name]: kp.alertmanager[name] for name in std.objectFields(kp.alertmanager) } +
{ ['blackbox-exporter-' + name]: kp.blackboxExporter[name] for name in std.objectFields(kp.blackboxExporter) } +
{ ['grafana-' + name]: kp.grafana[name] for name in std.objectFields(kp.grafana) } +
{ ['kube-state-metrics-' + name]: kp.kubeStateMetrics[name] for name in std.objectFields(kp.kubeStateMetrics) } +
{ ['kubernetes-' + name]: kp.kubernetesControlPlane[name] for name in std.objectFields(kp.kubernetesControlPlane) }
{ ['node-exporter-' + name]: kp.nodeExporter[name] for name in std.objectFields(kp.nodeExporter) } +
{ ['prometheus-' + name]: kp.prometheus[name] for name in std.objectFields(kp.prometheus) } +
{ ['prometheus-adapter-' + name]: kp.prometheusAdapter[name] for name in std.objectFields(kp.prometheusAdapter) }
